There is an ongoing debate about whether it is better a night owl Or initial, new evidence suggests Night sailors are about 50% more likely to developing type 2 diabetes Compared to those who declare it to be night too early.
People who live in darkness have a habit of sleeping late and waking up late. This behavior has been linked to a disease. higher chance of tobacco use and unhealthy eating habits, putting them at risk for obesity and type 2 diabetes, a chronic metabolic disease.
“However, we believe that lifestyle cannot fully explain the association between a late-onset chronotype and metabolic disorders,” said study researcher Jeroen van der Velde, from Leiden University Medical Center in the Netherlands.
“In addition, while it is known that a late chronotype is associated with higher [body mass index]”It is unclear to what extent chronotype affects body fat distribution,” van der Velde said.
His team studied the relationship between sleep timing, diabetes and body fat distribution in more than 5,000 people enrolled in the Netherlands Epidemiology of Obesity study.
The volunteers, most of whom were in their 50s, reported their usual waking and sleeping times.
The participants were divided into three groups – early chronotype (the first 20% of participants who slept the earliest), late chronotype (the last 20% of participants who slept the latest) and intermediate chronotype (the remaining 60%).
The participants were tracked for about seven years – during this time, 225 people were diagnosed with type 2 diabetes.
After adjusting the results for lifestyle factors such as age, sex, education, total body fat and physical activity, diet quality and alcohol consumption, researchers determined that participants with a late chronotype had a 46% higher risk of diabetes than those with an intermediate chronotype.
Van der Velde said the results indicate that the increased risk of diabetes due to having a late chronotype cannot be attributed to lifestyle alone.
“A possible explanation is that the circadian rhythm or body clock in late chronotypes is out of sync with the work and social schedules adopted by society,” he argued. “This could lead to circadian misalignment, which we know can lead to metabolic disturbances and ultimately type 2 diabetes.”
Van der Velde's team expected that early chronotypes would have the same risk of diabetes as intermediate chronotypes — they found that early chronotypes actually had a slightly higher risk, but “this was not statistically significant.”
The researchers also found that people with a late chronotype had higher BMIs, larger waist circumferences, more visceral fat — the harmful fat wrapped around internal organs — and greater liver fat content than those with an intermediate chronotype.
“People with a late chronotype have a higher risk of developing type 2 diabetes than those with an intermediate chronotype, possibly due to greater amounts of body fat, including more visceral fat and liver fat,” van der Velde said.
“The next step is to study whether people with a late chronotype have improved metabolic health when they change the timing of their lifestyle habits,” he added.
Those who stay awake at night should take care stop eating at a certain timeThe timing of meals, such as 6 p.m., can affect digestion and metabolism, because the timing of meals can affect digestion and metabolism, van der Velde said.
“There is no proof yet, but when the time comes our goal is to provide specific advice regarding the timing of lifestyle behaviors,” van der Velde said.
Their findings — which will be presented this week at the annual meeting of the European Association for the Study of Diabetes — follow recent research that suggested being a night owl could be detrimental to diabetes. Good for your cognitive function And Bad for your mental health,

“Cortisol and stress further increase glucose levels and promote weight gain,” Roslin, who was not involved in the new study, told The Post. “Weight gain increases the likelihood of sleep apnea and insulin resistance. It's easy to see the ball heading downhill.”
